building 2.3 short block

So I bought a 2.3l dura to build. I have the head at the shop getting a 3 angle valve job and resurfacing. It has stock 2.3 valves, crower springs and titanium retainers and stage 1 crane cams.


The bottom end I plan on buying supertech 11.6:1 pistons and Eagle rods. keeping the stock crank and will be buying a bsd.

This is my first engine build so naturally I have questions...


Should I be close to 200 hp? Of course I will dyno it but it doesn't hurt to get excited about it.
- I have a cossie IM, header, fs exhaust, and basically every bolt on you could have lol.

Can I use the stock head gasket or do I need a cometic one and how do I determine what thickness?

Any tips on putting it all together? I know I need to hone the cylinders and whatnot. What about removing the crank?


Before anyone says anything about tuning.... Tom does my tuning lol.

thanks all!

Head gasket thickness will change your compression ratio. There are calculators you can use. Also depends on how much is decked off the cylinder head, if the block gets decked, and how deep in the hole your new pistons and rods are when reassembled. I don't know about super tech pistons, but all V8 pistons are .020" down the hole compared to factory to make up for decking the block and heads.

If removing the crankshaft is a mystery, you really need to read a book or two on engine assembly.

I'd check the bores for taper 1st. That tell you if you need to bore it & how much or if you can do a light clean up hone or dingo ball it. The next oversize is half a mil= 87.5. You also need to check the crank jornals too. Are you going to have the rods & pistons & crank balanced? I'd take the block & crank to the machine shop & have them look at them & get the block boiled out. How many miles on the motor?

The shop weighs all the pistons & machines the heavy ones & for the rods, machines the pads of the rods on a jig. for the crank it gets spon up w/ bob weights on the rod jornals. Its probality not nessasary. For sure the clearences are. Tell the shop what rings your using also. Hey Chris I tried to call you.

So with balancing of the crank, I am assuming that I need to get that done even if I buy the ranger crank in order to be balanced with the pistons and rods?


Am I better off sticking with the stock crank and just spending the $30 for the bsd from massive?

Or should I just stay with the stock 2.3 crank and get everything balanced.

If you change the crank, rods, or pistons, then you need to rebalance them.
